Ruddlesden geotechnical

Ruddlesden geotechnical provides ground investigation, geotechnical consultancy and contamination assessment services.

Based in Exeter, but covering the whole of the UK, albeit primarily concentrated in the South West, Ruddlesden geotechnical was formed in 2004.

Ruddlesden geotechnical works on behalf of a wide client base, including local, regional and national housing developers, housing associations, commercial developers, building contractors, structural and civil engineers, architects, building consultants, quantity surveyors, local authorities and private individuals.

Development projects range from single dwellings and extensions to large housing estates, multi-storey flats, offices, industrial units, roads, slopes, schools, hospitals and basements.

The services and projects listed on this web-site provide an indication of those undertaken by Ruddlesden geotechnical, but others are carried out. If your requirement is not readily identifiable on this web-site, please contact us as we may still be able to help you.

    LiDAR, UAV and GIS used for Slope Stability Assessment

    Geoff Davis has recently been working on another coastal caravan site with slope stability problems.On this site, Lewis Brown Chartered Land Surveyors used remote sensing (LiDAR (Light Detection and Ranging)) from a UAV (unmanned aerial vehicle) to help understand the locations and magnitude of ground movements.Ruddlesden geotechnical then used GIS (Geographic Information System)  to highlight areas of concern, to quantify the degree of movement, which might have otherwise been missed.These technologies have been great in helping us understand the landslide processes at this site and, equally importantly, convey to others what is happening. However, they are of little use without a detailed understanding of the geological and geomorphological processes, which inform the all-important ground model, i.e. they should be seen as a useful tool to help us understand and communicate landslide processes, rather than a replacement for the understanding of them.

    Earthworks Specification, Devon

    Following a materials suitability assessment, Ruddlesden geotechnical produced an earthworks specification for the proposed material movements at a residential development site in Paignton. The specification summarised suitable and unsuitable materials present (based on the findings of the materials suitability assessment) and provided details of how to excavate, stockpile and deposit the materials. Guidance on the testing requirements (to confirm the material was suitable for placement/ conformed to those suitable materials detailed within the specification) was also provided. Ruddlesden geotechnical also carried out the earthworks testing for this project.

    Ground Investigation Report, Cornwall

    A Ground Investigation Report, fulfilling the requirements set out in BS EN 1997-2: Ground Investigation & Testing, was produced for an extension to a school in Dorset. The Ground Investigation Report (GIR) presented a factual record of the ground and groundwater conditions encountered, together with the laboratory testingresults, followed by a review of the ground profile and geotechnical parameters for foundation design. The Ground Investigation Report was issued promptly, shortly after the receipt of the laboratory testing results, less than three weeks after the completion of siteworks. Interim parameters for design were provided prior to the receipt of the laboratory testing results, based on field observations and in-situ testing results.
